Your idea will not work as presented, here's why: Your motherboard is an AM3+ (AMD) motherboard, an Intel CPU will not fit nor work on that motherboard. Simply put, you can only put AMD CPU's on an AMD motherboard. Another limitation to the motherboard is the use of a processor of 95W or less (I'm taking that as meaning less than 95W) since your motherboard recommends against running burn-in/stressing programs to avoid possible heat damage found here http://us.msi.com/product/mb/760GMP23_FX.html#/?div=CPUSupport
What about your current PSU, what do you have going on there? Make and model preferably.
